Dear Sir,
we met a disaster with our 62.5 kva genset, after rewinding
we informed by our contract engg that due to return current
coming in neutral & impropper earthing this happend.
But after all set up & load balance we checked & found
again we have about 20 to 32 amp return current on neutral.
we have 12 airconditioner + 12 mini fridge on single phase
line.
Pl suggest any idea to solved this problem

I think imbalance load is main reason of this problem and cross current compensation instrument transformer should be installed on your common bus bar to prevent this loss
but balance load all of 3 phase eleminate the highest neutral current.
